Abstract
A photoelectric converter element is constituted by an electrical charge storage capacitor and a photodiode connected in parallel with the capacitor. A plurality of the photoelectric converter elements are aligned or arranged in a line, each of the photoelectric converter elements has one end thereof connected in series with a switch, a plurality of the photoelectric converter elements have the other ends thereof commonly connected with a line, and the common line is connected with a series circuit including a resistor and a d-c power source. When the switch is turned off, an electric charge stored in the storage capacitor is discharged correspondingly to amount of light received by the photodiode. On the contrary, when the switch is selectively turned on, the storage capacitor is charged with an electric charge corresponding to amount of discharge. Electric signals representing the amount of charge is then supplied to the common line.
